My system is used in a home/office environment, mainly as a backup target for PCs and Macs. Backups either use Acronis (full / incremental) or Time Machine.
The pool containing the backups is then replicated on to a set of external drives that are used for off-site backup, with the backup disk being rotated off-site once a week. The replication uses a "Replication Task" to duplicate snapshots of the pool that are taken hourly, daily, weekly, monthly.
However the Time Machines backups include a similar snapshot strategy produced by Time Machine itself.
Does this mean that I only need to store a smaller set of ZFS snapshots for a Time Machine share (e.g. two, to recover if Time Machine creates an invalid backup)?
